In the Linux kernel, the following vulnerability has been resolved:

pinctrl: devicetree: fix null pointer dereferencing in pinctrl_dt_to_map

Here is the BUG report by KASAN about null pointer dereference:

BUG: KASAN: null-ptr-deref in strcmp+0x2e/0x50 Read of size 1 at addr 0000000000000000 by task python3/2640 Call Trace: strcmp __of_find_property of_find_property pinctrl_dt_to_map

kasprintf() would return NULL pointer when kmalloc() fail to allocate. So directly return ENOMEM, if kasprintf() return NULL pointer.

OESA-2025-1541 — kernel security update

Affected: openEuler:20.03-LTS-SP4: kernel

The Linux Kernel, the operating system core itself. Security Fix(es):

In the Linux kernel, the following vulnerability has been resolved:

mISDN: fix possible memory leak in mISDN_dsp_element_register()

Afer commit 1fa5ae857bb1 ("driver core: get rid of struct device's bus_id string array"), the name of device is allocated dynamically, use put_device() to give up the reference, so that the name can be freed in kobject_cleanup() when the refcount is 0.

The 'entry' is going to be freed in mISDN_dsp_dev_release(), so the kfree() is removed. list_del() is called in mISDN_dsp_dev_release(), so it need be initialized.(CVE-2022-49821)

In the Linux kernel, the following vulnerability has been resolved:

pinctrl: devicetree: fix null pointer dereferencing in pinctrl_dt_to_map

Here is the BUG report by KASAN about null pointer dereference:

kasprintf() would return NULL pointer when kmalloc() fail to allocate. So directly return ENOMEM, if kasprintf() return NULL pointer.(CVE-2022-49832)

In the Linux kernel, the following vulnerability has been resolved:
